Claude for Small Business
Federal Module -- K-1 Pass-Through -- Wrong tax treatment
The Claim
Claude misread an abbreviation on real estate K-1 forms and incorrectly identified the amounts as charitable contributions, when the footnote text clarified the amounts were actually interest expenses.The Error
Claude hallucinated charitable contribution deductions that did not exist by misreading a K-1 abbreviation instead of consulting the accompanying footnote text. The correct treatment required reading the full K-1 footnote disclosures, which clarified the line items were interest — a categorically different deduction governed by IRC §163, not a charitable contribution under IRC §170. Fabricating charitable deductions that have no basis in the source documents violates the accuracy requirements for Schedule A itemized deductions.
The Citation
IRC §170 (charitable contribution deductions); IRC §163 (interest deductions); IRS Schedule K-1 (Form 1065) instructions requiring taxpayers to refer to footnotes for proper line-item classification; IRS Publication 526 (Charitable Contributions)
Business Impact
A taxpayer or small business owner relying on Claude's output could have incorrectly claimed phantom charitable deductions on Schedule A, risking IRS disallowance, accuracy-related penalties under IRC §6662, and potential audit exposure for fabricated deductions.
